Advantageously, the touch film layer can support a wide range of diverse user interface systems, including user interface systems with various types, layouts, and/or languages. The touch film interface system, for example, can include multiple touch film layers that provide a variety of user interface systems and that can be used in the alternative. Alternatively, the touch film interface system can include a projection system for shining the selected user interface system onto the touch film layer.
